Application filed July 12, 1905. Serial No. 269,296.

To all whom itlmay concern:

Beit known that I, MoNTIEBLEvINs MINER, a citizen of the United States, and a resident of Sampson, in the county of Douglas and Oregon, have invented a new and Improved Friction-Set, of which the following is a full, clear, and exact description.

The invention has reference especially toa device for setting the friction-pin'of hoistingengine drums, although it is useful in other connections, as will hereinafter appear.

The object ofthe invention is to reduce as much as possible'the friction incident to the operation of setting or moving the friction-pin in a aratus of the class referred to attain by a peculiar arrangefriction, devices and the adaptation of other peculiar friction devices to coact between the actuating-screw, head, box, and friction-pin in such'a manner as practically to absorb the friction between the moving parts, rendering the device more durable and easier of operation and increasing the mechanical efiiclency of the hoisting-engine. I The invention resldes 1n certaln novel features of construction and arrangement of parts, which will be fully setforth hereinaf- In Fig. '1, 00 indicates part of the bed of a Y hoisting-engine, and b one of the drums or the drum thereof, theshaft of which is mounted on the bed in bearings, one of which is illustrated at c.

In Fig. 2, dindicates the-shaft of the drum, and e the usual friction-pin, which passes through the shaft and serves to operate the clutch for throwing .the drum l) into action. Attached to the shaft d is the box f, in. the outer end of-which is located the tubular portion g of the head g. h indicates a means for holding the head gand its .part g stationany, which means may 'be-of-any-desired sort.

dependently of said head.

i indicates the operatingscrew, which is threaded in the tubular part g of the head 9 and is provided with a handle i, facilitating the operation of the screw. "5 indicates studs on the end of the screw 61, adapted to be en- I gaged by a tool of any sort to facilitate adjusting the screw with reference to the handle. Operating between the head 9 and the outer wall of the box f and located within .said box is an an'tifriction bear-ing means comprising a disk is, formed with radial openings k receiving antifriction rollers 76. These rollers 7c run against wear-plates P, which are arranged one at each side of the disk is and bear, respectively, against the box f and the head 9. These devices serve to take up the friction otherwise existing incident to the rotation of the boxf on the head 9. f indicates a packing which surrounds the tubular part g of the head gand is located in a cavity formed in the outer wall of the box. f, the adjacent wear-plate 76 serving to hold the acking in place. Located in the box f at the inner side of the head g is a disk or wear-plate Z, formed with openings 1, in which pins 9 projecting from the head, are

loosely received, whereby to hold the disk 1 stationary with the, head, but to permit the disk to move longitudinally of the shaft (1 ini indicates a button or hearing member which is engaged between the inner end of the screw 4. and'the I disk Z to reduce the friction between these parts, due to the turning of the screw. Engaging the friction-pin e is a disk m,.sim i1ar to the disk Z and having openings m re'ceiv ing ins f }projecting from the inner wall of the ox f, .t us allowmg thedisk m to move freely axially of the shaft d, but causing said disk to rotate continuously with the box and shaft. Located between the disks Z and m is a carrier or cage-disk n, this disk being formed, as shown in Figs. 2 and 3, with openings n, which receive antifriction-rollers n these rollers bearing against thedisks land a to reduce friction incident to the independ ent or relative rotary movementof said parts. The disk m engages the frictionin e, and u on moving said in axially of t e shaft (1 t e friction-pin Wil be moved to'operate the clutch, as will be understood from the prior art.

ing "that it is employed as a friction-pin set for hoisting-engines, when it is desired to move the .pin 0 and set the friction-clutch In the operation of the apparatus, assum- IIO 25 tain part of the friction thereof.

the handle 4/ should be operated to turn the screw '11. The head 9 and its tubular end g being held stationary by the device h, the screw Lwill thus be advanced toward the friction-pin, pushing the parts from the position shown in Fig. 2 and causing the elements Z, n, and m to move leftward, pushing ahead of them the friction-pin e and causing them to operate in the friction-clutch. This to will start the revolution of the drum 1).

When it is desired to arrest the movement of the drum, it is only necessary to reverse the direction of movement of the handle i, thus returning the screw to the osition shown in Fig. 2 and allowing the dis is Z, n, and m to recede from their position to ermit the return of the friction-pin. It wi 1 be observed that this arrangement provides effectually for the elimination of practically all of the appreciable friction due to the operation of 0 Having thus described the preferred form of my invention, what I claim as new, and desire to secure by Letters Patent, is
